Package Includes:

(1) Differential Master Bearing Install Kit

- *Note: The Dana 70U has a carrier break at 4.10 & numerically lower/ 4.56 & numerically higher. That means if you have 3.54-3.73 ratios from the factory, and would like to run 5.13-5.86 ratios, you will need to buy a new carrier. Contact support if you need help figuring out what carrier you have.
